OK. If you want to create a GUI, what you want to do is the following:

#include <GUIConstantsEX.au3>Opt("MustDeclareVars",1);This means you are required to declare ALL variables.Local$winhandle,$progress,$percent=0;This is where the variables are declared$winhandle=GUICreate("(Give it a title)",300,100);This creates the actual GUIGUICtrlCreateLabel("Example of a progress meter",30,30);Displays text on the GUI$progress=GUICtrlCreateProgress(30,60,250);This creates the progress barGUISetState();By default, the GUI is hidden, and you must bring it forward.While1;Set a loop so the program wont closeGUICtrlSetData($progress,$percent);This is the part that actually changes the progress bar.;What we are going to do is make a variable called $percent and;increment that so we are always adding data when we want.$percent+=1;This will go up by 1 percent every time it is run.IfGUIGetMsg()=$GUI_EVENT_CLOSEThen;This checks to see if the close button is pressed...GUIDelete($winhandle);This deletes the GUI created at the startExitLoop;and breaks out of the while loopEndIf;Ends the if statementWEnd;This ends the loop.

All this will do is make the progress bar keep loading up. NOTE: It will go past 100%

Anyway, I heavily commented it for your benefit so I hope this helps you understand a bit better, if you want to get into GUI programming, it is not that hard. You just need to give about a week. I was loosely programming GUI's in AutoIt (whilst referring to other GUI programs and the help file ALOT!!!) within my first day of knowing the language, and you can do the same.

If you really want to get into GUI programming, your best bet would be to make another thread asking for an outline.
